What are some ways to handle JavaScript exceptions effectively?

Within my application, I am retrieving the content from a different domain's page. This content includes specific JavaScript that is executed alongside the page. However, there is an issue with the following line of code within the JavaScript: "document.selection.createRange()". This results in an exception being thrown at runtime in Internet Explorer due to security restrictions preventing changes to iframe data.

My query is centered around how to handle or suppress this particular exception effectively. Any guidance on this matter would be greatly appreciated. Thank you in advance :)

Answer №1

To achieve this in jQuery, simply employ the load method along with a specific page fragment.

When using .load() with a selector expression added to the URL, scripts are removed before updating the DOM, preventing them from being executed.

However, keep in mind that this approach will only be successful if the external domain permits access to your domain through CORS HTTP headers.
